Many of the special effects were painted and animated (cg and cel). Granted, the motion of the film was carried by live acting, it was a great mix of new animation techniques, and skilled acting.

Not so much what was created in the '80s but what I discovered for the first time in the '80s....

Anything Ralph Bakshi, pre Studio Ghibli projects, The Hobbit by Rankin Bass, the original series of Johnny Quest, just to name a few. Also artists who may not have been animators, but drew some fantastic comic and cartoons!
